本文讨论了双金属共存体系M_1-M_2-x-y,当两种金属的化合物相互作用生成多金属化合物时,优势区相图的绘制原理、方法及计算机程序。通过绘制Zn-Fe-SO系的优势区相图,分析了ZnO·Fe_2O_3的生成及稳定条件,并说明了其在硫化锌矿焙烧中的指导作用。
Discussions were made of the principle, method and computerizedprogram for drawing the predominance diagrams of the bi-metal co-existed systemM_1-M_2-x-y in which the multimetallic compounds may be produced by interactionbetween compounds of both metals. The formation of zinc ferrite and its stableregion have been analyzed through drawing Zn-Fe-S-O system predomincance dia-gram. The availability of the diagram is given the direction to roast the zinc sul-fide ore as well.
